Re: Filter Out Objects


Lynn Deffenbaugh
 

Actually, these are using the "SOTA" symbol instead of the X that I saw yesterday.  A filter term of:

-s//;/S

should knock them out since the SOTA symbol is an S overlay on the ; alternate table symbol.

And these objects ARE on the APRS-IS network, it just depends where you are and whether or not any of them is within your range.  There are 44 active objects world wide with this symbol in the past 2 hours.

So Randy was correct. "-b/ON6ZQ" should block all of these, but will also block any other traffic from ON6ZQ, which may or may not be a good thing for you.  A second choice in blocking filter might be "-u/APN100" but that will block any packets with APN100 in the "to call" field, and also may or may not be what you want.  I am unfamiliar with the app being used here, so I can't tell you how to enter server side filters on it.

It appears those objects are "Summits on the Air" (SOTA) peaks being injected into the server your friends application is using.  That might explain why we do not see sota peak objects on APRSIS32.  Maybe changing the server to one that doesn't include sota peaks out might be helpful.  For example when I use firenet, I filter out the water station objects so they don't  clutter my screen.  I don't have to filter those objects out when I use one of the rotate.aprs2.net servers because they aren't sent on by that group of servers.  Try noam.aprs2.net to see if they no longer show up. 

Be sure to clear out all of the objects after changing filters or switching servers so you can see if there is any improvement.  The objects may take several hours to time out if you don't.
